Grouting reinforcement construction method for water-rich liquefied silt stratum
The invention discloses a grouting reinforcement construction method for a water-rich liquefied silt stratum in the field of building construction. The grouting reinforcement construction method comprises the steps of investigation and research, drilling and grouting equipment installation, slurry preparation, grouting and hole sealing. During grouting, grout is output from the grout outlets with different heights through rotation of the grouting pipe, hole-dividing grouting is achieved, the pressure of the grout is balanced, and the problem of ground collapse caused by aggregation of the grout is solved. And meanwhile, the slurry is output by centrifugal force generated by rotation of the grouting pipe, and the pressure when the slurry is output is increased. An auxiliary block, a baffle, a first spring and a discharging opening are used for controlling output of grout, when the amount of the grout in a grout outlet channel is gradually increased, the discharging opening is gradually blocked, and the grout only flows out of an auxiliary hole; when the amount of the slurry in the slurry outlet channel is reduced, the auxiliary block is pushed back to the original position by utilizing the elasticity of the first spring, so that the slurry is discharged regularly and quantitatively. Therefore, while the grouting pressure is increased, the grouting pressure is balanced, and the reinforcing effect of the water-rich liquefied silt stratum is improved.
本发明公开了建筑施工领域的一种富水液化粉砂地层注浆加固施工方法，包括考察研究、钻孔并安装注浆设备、浆液制备、注浆和封孔。注浆时利用注浆管转动将浆液从高度不同的出浆口输出，实现分孔注浆，使浆液的压力平衡，避免了浆液的聚集导致地面塌陷的问题。同时，注浆管转动产生的离心力将浆液输出，增大了浆液输出时的压力。利用辅助块、挡板、第一弹簧和出料口对浆液的输出进行控制，当出浆通道内的浆液量逐渐增大时，逐渐将出料口进行封堵，使浆液仅从辅助孔流出；当出浆通道内的浆液量减小时，利用第一弹簧的弹性将辅助块推回至原位，由此使浆液定时定量排出。由此在提高注浆压力的同时，使注浆压力平衡，提高富水液化粉砂地层的加固效果。
